FIELD: fire safety.
SUBSTANCE: method of explosion-proof vacuum pumping of sealed enclosures in production of polymeric composite materials is pumping the air with vapours of highly-flammable liquids from the sealed enclosures using a vacuum pump through distribution units, pipelines and vacuum receiver. At that after each vacuum pumping the receiver, the distribution units and the pipelines are filled with gas-deterrent.
EFFECT: narrowing of ignition area or complete elimination of the possibility of burning of the mixture of air with vapours of highly-flammable solvents.
